Abstract BACKGROUND: Grape juice consumption may prevent several chronic diseases owing to the presence of phenolic compounds, which have an important role in the reduction of oxidative stress. This study investigated the polyphenol content and antioxidant activities of grape juices from two cultivars: BRS-Cora and Isabella. Total polyphenol content (TPC), anthocyanins, antioxidant capacity (oxygenradical absorbance capacity, ferric reducing antioxidantpower and1,1-diphenyl-2-picrylhydrazyl), and phenolic profile (high-performance liquid chromatography with diode array and fluorescence detection ? HPLC-DAD-FLD) were determined. RESULTS: BRS-Cora grape juice showed higher concentrations of total polyphenols and anthocyanins, as well as higher antioxidant...

Functional tea from a Brazilian berry: overview of the bioactives compounds. Repositório Alice

The consumption of berries has become a trend with confirmed health properties; however, fruit peels have been wasted despite their high concentrations of bioactive compounds. Tea made from jaboticaba (Myrciaria jaboticaba) peel (JP) could be an alternative to make use of this byproduct and contribute to increased intake of polyphenols. For this reason, this study investigated the JP chemical omposition and bioactive profile, as well as the antioxidant capacity of its aqueous extract (JPT e 25 g L1). The peel corresponded to approximately 35% of fruit weight. Total fiber content was approximately 30 g 100 g1, and the soluble portion represented 8.50 ± 0.21 g 100 g1. JPT showed strong antioxidant capacity according to all methods tested (FRAP, DPPH, and...

Tropical Isabella grape juices: bioactive compounds and antioxidant power depends on harvest season. Repositório Alice
CAZARIN, C. B. B.; CORREA, L. C.; SILVA, J. K. da; BATISTA, A. G.; FURLAN, C. P. B.; BIASOTO, A. C. T.; PEREIRA, G. E.; RYBKA, A. C. P.; MARÓSTICA JUNIOR, M. R..
Grapes are important sources of antioxidants compounds and one of the most used varieties to elaborate juices is 'Isabel', or 'Isabella', as it is called in North-America. This study aimed to evaluate the antioxidant activity of Isabella grape juices from the tropical semi-arid climate produced in Brazil on March and September, 2010. Total phenolics and anthocyanins were determined, as well as the antioxidant capacity by DPPH, FRAP and hydrophilic ORAC methods. Test T was used to compare statistical difference at 5% of significance level. As expected, the results showed that the season can play a significant role on phenolics content and antioxidant power. Polyphenols content in juices varied from 82.9 ± 0.92 to 102.2 ± 1.59 mg GAE 100 mL-1 and...
